Here are some plants that people will always buy and can build you a good customer base, that can help make you rich:

Sweet Peas

These fragrant old favorites need to get their first spurt of growth before the weather warms too much.

Colors range from purest white through all shades of pink and lavender. Soak the seeds in warm water over night. Plant one seed to a 2-inch pot of rich soil. February is a good time. Grow them right on in the cool greenhouse or, after the plants have started into good growth, say mid-March, move them to the cold frame.

Cuthbertson's heat-resistant sweet peas are a good choice for repeat business. These come in all the favorite colors. The Spencer and Zvolanek strains also are well known and thoroughly reliable.

Zinnia

Zinnias have been so improved that now there are forms for every gardening need. There are the baby zinnias, the bedders, the small-flowered sorts (so good in flower arrangements), the improved "giants," and the cactus types with twisted petal tips.Flowers range from white through yellow, orange, pink, and red, and multicolored.

Sow the seeds in April in flats and grow them in the cool greenhouse. Prick off and plant singly as soon as they are easily handledperhaps in 2 weeks. Grow under strong light. Once potted, they can be removed and placed in the cold frame, thus leaving space for starting another crop for the later buyers

Here are some great and profitable plants for terraces:

Anemone

These pretty bulbous plants thrive in sun or semishade. Their flowers are like thick-petaled poppies, in red, purple, or white. For summer-flowering plants, start the corms (with "claws" pointing downward) in March in the cold greenhouse. As soon as growth shows, pot up in 3-inch pots of porous soil mixture.

Anemones can be started from seeds sown in July, but the imported corms sold in mixture are so reasonably priced it hardly seems worth while to grow them from seeds.

Astilbe features graceful foliage and feathery flower spires. Large clumps can be divided in the spring and potted in 5- or 6-inch pots of sandy soil. They need plenty of water and should be grown in a warm house. Astilbe forces well for late winter early spring bloom.

Baby's Breath (Gypsophila elegans)

The lacy appearance of baby's breath makes it a welcome addition to the terrace. The freshly cut branches are beautiful in flower arrangements. When dried, they become material for winter bouquets.

Balloon Flower (Platycodon grandiflorum)

Neat growth, handsome flowersin bud or bloommake the balloon flower a favorite with gardeners. It is a hardy perennial with blue, purple, pink, or white flowers. Just before Although you can start them from seed by sowing them in a warm house in the spring, it may be more profitable to purchase rooted cuttings, or a few large plants and propagate your own cuttings.

As soon as seedlings show true leaves, and cuttings sprout new leaves, give them weekly dosages of diluted liquid fertilizer. One-fourth the recommended proportion is right for seedlings; dilution for cuttings.

The older plants are rested through the winter by storing in a cool place. Start the plants into growth in February or March. As soon as they show strong growth, take cuttings and insert them in flats of good greenhouse soil. If the cuttings are given bottom heat so the soil temperature is about 60 degrees, they will root and be sturdy enough in 3 weeks to pot into 3-inch pots. Encourage growth by growing them on in a warm greenhouse or by giving them another 2 or 3 weeks of 60-degree bottom heat.

They can be sold directly from the 3-inch pots; or, if you desire larger plants, give them another shift into a 5- or 6-inch pot.

Cuttings taken in September and grown in 60-degree temperatures without any bottom heat will produce plants for 4-inch pots the following spring.

Passiflora

The passion flower is a wonderful and "different" vine for terrace trellising. The flower range is from creamy white through lavender, blue, and pink to red. Propagate passiflora during the early spring by taking cuttings and inserting them in any rooting media. They grow well at 70 degrees and can be planted directly into 2- or 3-inch pots.

They will flower sparingly in these containers, but they can be sold before flowering because as soon as prospective buyers note the name passiflora, they are eager to purchase.

A Minnesota grower propagates passiflora by the hundreds and still falls short of supplying the demand. My own greenhouse is so crowded with other things that I lack space for a collection of these vines, much as I would like to have them. Unrooted cuttings sell for 35 cents to a dollar each, depending on the relative scarcity of the particular variety.

Highly unusual varieties can be produced by planting passiflora seedwhich is somewhat difficult to germinate but can be helped along by an overnight soaking in water. Plant in a light soil and keep in a 70-degree house. Germination takes from 2 to 6 weeks. If you want to grow them on yourself in order to have material for cuttings, keep shifting until the vine is in a 5- or 6-inch pot.

In the summer they can be transplanted to the garden; and if your greenhouse can accommodate these big plants, you can dig them in the fall and replant into 8- or 10-inch pots. These older plants will provide you with hundreds of cuttings.
opening, the buds become swollen and resemble balloons, thus its common name. There are single and double flowers; plants to 2- and 3-foot heights, or dwarfs. These make especially good terrace material.

Start seeds in late February or early March in shady loam and grow in the cool greenhouse. Pot up in 3-inch pots about 6 weeks after seed planting.

Candytuft (Iberis)

Flower spikes much like hyacinths, in shades of white, pink and orchid, make these low-growing plants favorites for terrace plantingsespecially as a planting to top a rock wall.

Plant seeds in mid-January and grow them in the cool greenhouse. These will produce flowering plants for sale in May. Sow thinly in flats of soil, transplant to 3-inch pots about March first.

Carpet Phlox (Phlox subulata)

It is not uncommon to see large areas of terrace given over to this richly colored, spring-flowering perennial. Although you can start carpet phloxalso widely known as mountain pink from seed, the plants from which you can make divisions are so reasonably priced that it is not practicable for small greenhouse growers to devote space to seed starting. Plant the divisions in small flats of ordinary soil, give them good light and plenty of water. Grow in the cool greenhouse.

Fuchsia

With their drooping, richly colored, bell-shaped flowers, fuchsias make beautiful potted plants for the terrace, for growing in the outdoor planter, or the cool, well-lighted window garden.

Sweet peas should be transplanted to the garden just as soon as danger of frost is passed. They grow best in cooler weather, which is a special sales approach to use on the gardener who just can't wait as late as May to get his spade in the ground.
