I planted my spotted calla lilly in a mostly shaded garden with dappled light in the morning and afternoon. It is not only thriving but it has become the highlight of the corner it is in! It has come back now for its 2nd year, I planted in May of 2011. It is in a protected spot, about 2-3 feet off the foundation of the house and is in a corner so has protection on two sides. The spotted leaves look fantastic long before it blooms in June in 7B. I would not put this plant in sun as it seems very happy in shade and blooms prolifically with only shade conditions. I will also say I deeply soak the plant about twice a month to make sure it's getting plenty of moisture but in arid southern maryland it has survived quite a lot and long period of drought. I WOULD LIKE MANY MORE

This was the first Zantedeschia that I ever grew. The first in far too many. I suggest this vigorous Zant. for the beginning calla grower and seasoned gardener as well. I also suggest liberally mixing bone meal into its soiless potting mix. High perlite is good, as drainage is absolutely critical for long-term or large-quantity cultivation of this plant. Leaves can burn in hot, dry, full sun. Remove old flowers/seedheads as to not sap the energy from the corm, unless you want seeds.
Screwy flowers the first year are a result of the overuse of flowering hormones on the bulb by the grower.
Planting in-ground in makes for much better plant by providing the roots with a cool place to take in moisture, as compared to pots which may heat up and rot the roots/bulb.
Seeds are an easy and bountiful way to increase your Z. albomaculata. Leave the seed head until the stem itself and the faded bract ("petal") are dry. Harvest and hang until the fruity coverings dry as well. It will be foamy when dry, and can be orange, gold, or light green. Clean the fruit off of the seeds and store cool and dry. They will remain viable for a number of years.
Plant seeds .5-1cm deep in a well-drained soilless media, mixed with rinsed sand or perlite. Moisten and cover. Germination in one month or less gives rise to unspotted seedlings. Fertilize regularly to build corm size. Blooming size can be reached in 2-3 growing seasons.
Overwintering in-ground zones 6b and warmer: (and perhaps cooler)
Choose a well-drained site with loose, humusy and airy soil. (Southern exposures are best) plant 10-15cm/4-6in deep in spring, and treat the plants well over the summer. After frost, remove the leaves and mulch with a deep but loose mulch 15-30cm/6-12in. *As long as the soil around the corm is drained and unfrozen, and the bulb grew in the site during the past growing season, it will survive to come up in late spring.

I have no idea what variety this is. The package was marked "midnight eclipse" and after seeing it's first bloom and then doing a little research I realized that was wrong. Regardless I was still pleased with the plant.
Its my first time planting from a seed. This plant proves to be easy to take care of. I enjoy watering it every morning as soon as the sun shines and I love watching it grow everyday. You can always see a difference on its growth & that is what's so fascinating for me. I love them and can't wait for them to bear flowers :)
