What’s wrong with my giant calla Lily?

[finder003]

Hi everyone...my first post here!
I planted bulbs in the ground in April. Here in zone 9b giant calla lilies bloom in early spring in Feb - March. So I put the bulbs in after the bloom period for my zone. I obviously don’t expect flowers this year (or even next) but I expected the foliage to be lush during the growing season. I planted 2 groups in sets of 3 and as you can see from the first picture, the leaves are stunted and curled. The second one looks slightly better.
I do think they need to be moved to an area where they get more sunlight (currently they get only 3-4 hrs) but that shouldn’t affect foliage - correct? They do get average amount of water. I can’t detect any disease.
Could the bulbs be too crowded causing the stunted growth?

Greetings, welcome to the Forums.

Your Giant or White Calla-lilies (Zantedeschia aethiopica) don't look to be in unreasonably poor condition, but you will get faster growth and large, lusher foliage with more water. White Calla-lilies are tolerant of a variety of conditions but most certainly reach their full potential in very well-watered, mesic conditions. They will well grow quite well at the margin of a pond or river. The amount of sunlight you mention is within acceptable bounds for this species. Mulch your plants regularly with a rich compost. This will both help retain water and provide nutrients to enhance growth.
