If you are interested in getting Calla Lilies for your garden, and are unable to get some friends or a neighboring garden to get you bulbs, then you may consider growing these White beautiful Lilies from seed. Here’s a complete article that describes how to grow the Lilies from seed (link). Here are some extracts from the article:

Before even thinking about planting the calla lily seeds one needs to sort out the best ones by pregrowing them a little. This is done simply by placing a folded damp paper towel on a plate and then spread out the seeds upon it.
There are a lot of reasons not to plant the seed straight out in the garden among birds and mice, there are a lot of dangers still out there for a little seed so the best thing is to preplant it in a small pot so it can grow strong and healthy in peace.

Nearly every single plant, or seed requires a growing zone it will grow in. You read about different types of plants, and almost every good information site will provide the hardiness zones that it will grow in, but you don’t know which zone you are in. This map will provide this information to you, either by clicking on a zone in the map, or in the list of state abbreviations below the map.

How to Use the New Map:
Zones 2-10 in the map have been subdivided into light- and dark-colored sections (a and b) that represent 5 F (2.8 C) differences within the 10 F (5.6 C) zone. The light color of each zone represents the colder section; the dark color, the warmer section. Zone 11 represents any area where the average annual minimum temperature is above 40 F (4.4 C). The map shows 20 latitude and longitude lines. Areas above an arbitrary elevation are traditionally considered unsuitable for plant cropping and do not bear appropriate zone designations. There are also island zones that, because of elevation differences, are warmer or cooler than the surrounding areas and are given a different zone designation. Note that many large urban areas carry a warmer zone designation than the surrounding countryside. The map-contains as much detail as possible, considering the vast amount of data on which it is based and its size.

Adding some white vines to your garden adds a lot of value, and adds a lot of variety. Some of the benefits that vines bring to your garden include:
1. Vines cover the space between fences and grills and bring a sense of privacy to your garden
2. Vines bring a good green effect to the boundaries of a garden, when grown on the edges
3. A flowering vine makes the place seem much more full of flowers and colors
4. Vines can cover an area that is otherwise dull and ugly, or where vegetation finds it difficult to take hold
5. Vines, when grown carefully and allowed to cover the upper part of a garden, bring a sense of a live roof to your garden (you can use them over wooden slats that cover potions of a garden). In times when the sun is harsh, a vine covered roof brings some shade to plants underneath
6. A vine can take a very small root space on the ground, but otherwise reach a much larger footprint over the ground
7. Mixing different types of vines ensures that the garden is always full of flowers; thus making the garden look better and attracting the butterflies and bees to your garden

There must be many more advantages, so if you can suggest more, please let me know.
