Gardeners' Notes:


On Jan 17, 2010, annlof from Camarillo, CA wrote:

Blooms profusely in spring and summer in SoCal. I consider this plant a low-growing shrub. Does fine with half-day sun; benefits from moderate pruning twice a year to keep it from getting leggy. Foliage looks good all year. In my experience this geranium seems to be less susceptible to the budworms which attack the zonal and ivy types.

Planted in west facing border with star jasmine in front and Indian Hawthorne behind. Beautiful color all year. I live in North San Diego County just inland from the coast.

Bought mine May 2003, it was pretty all summer, over-wintered it in our cool bedroom (usually 55-65 deg.) and watered infrequently. Took cuttings and rooted them in soilless mix successfully and now, May 2004, have 4-5 containers with Martha Washington 'Raspberry Swirl'. Quite happy with this plant.

we purchased two of these (Martha Washington) late this winter. They are doing well in containers. I am having some problems with a type of bee that is taking off pieces of the flowers. Any suggestions on how to fix this? Otherwise they are putting on very nice show.

Where hard frost won't kill them they should be grown in containers to keep them from taking off.

Shrubby, evergreen perennial.

Has rounded, slightly toothed, mid green leaves on stout stems. Bears very showy, large, velvety flowers ranging from pink, white, orange, purple and red which can be seen as selfs (single colour), bicolors, light or very deep colours which appear almost black. The flower heads can be up to 5-6 inches across, each flower being about 1.5 inches across. Double flowers are produced but most commonly singles.

Flowers from June-September outside.

Grows in well drained soil (not acid) and Regals prefer partial shade. They need a frost free position and dislike winter wet so best bought indoors until last frost date.
