Tina Dixon, of Plants à la Cart in Bothell, Washington, and Marsha Davis-Thomsen of Seattle are not easily discouraged by short days, rain, and persistently chilly weather. Each fall, just when everyone else in the Northwest is giving up on gardening for the season, the two designers whip up winter-into-spring plantings in containers.

Take the sumptuous mix of perennials, grasses, heathers, and spring-blooming bulbs they planted last fall in the sandstone urn pictured at left . It looked good almost instantly after planting - and heather foliage and pansy blooms provided color on a front porch through winter. Then, in spring, successive bursts of daffodil, grape hyacinth, and tulip flowers heightened the show.

Winter weather near Lake Washington did not faze this collection of plants; New Zealand flax, the most tender of the plants in the arrangement, is hardy to about 20°. Throughout the cool season, the plants needed no supplemental feeding, and weekly watering was only necessary during dry spells between rains.

Costs for this project (including soil, bulbs, perennials, and fertilizer) came to about $110. The sandstone urn costs more, but you can use any large container that catches your fancy, including terra-cotta.

 

 

PLANTING IN A POT

1. Fill the bottom of the 21-inch urn or pot with commercial potting soil.

2. Knock the largest plant out of its nursery pot, rough up its rootball, then plant it in the center or back of the large container.

3. Set the smaller plants - still in their nursery pots - atop the soil around the first plant. Move them around to fine-tune the design, then remove them.

4. Mix 9-9-6 bulb fertilizer into the soil (follow label directions), then plant the tulip and daffodil bulbs around the periphery of the container.

5. Remove the rest of the plants from their nursery pots, rough up the rootballs, and plant them over the bulbs according to your plan. Fill the spaces between plants with potting soil; tuck in tiny grape hyacinth bulbs.

6. Water thoroughly.
