| These are not full shade plants. They prefer some shelter from midday sun, but will grow tall and devoid of flower if grown in too much shade. If you have no choice but full sun then make sure they have ample summer moisture, not waterlogged ever. They will take full sun reasonably provided they have the moisture. Ideal conditions include a good rich deep soil, full exposure in winter, and light shade in summer, ie under a high canopy of deciduous trees in humous rich soil. I grow in a variety of conditions and provided they do not bake dry, full sun is almost as good as light shade. I get summer temperatured of 20-27C. Cheers Greenmanplants Hampshire England Zone 8-9 |
