Gardeners' Notes:

Neutral Baa On Nov 17, 2001, Baa wrote:

A perennial, cormous plant from South America.

Has lance shaped, mid-dark green, pleated leaves. Bears blue with a white basal stripe, short lived flowers in succession over several months. The flowers have 3 petals which are very slightly reflexed and (to me) give the appearance of a flattish Cyclamen.

Flowers depend on when corms are planted, if Autumn planted they will flower in Spring. If Spring planted they will flower in Summer.

They are hardy down to 32F only so best grown in a greenhouse in frost prone areas or lifted before first frosts, they may tolerate occasional air frosts in dry soils.

They like very well drained, rich soil in full sun and a sheltered site. They loathe wet soils even during summer so protect from heavy downfalls. I know this to my cost!
