Chocolate Mint Plant: This amazing leaf can be added to brownies, cakes and ice creams and even cocktails. You can even steep it in a cup of hot water to get the chocolate mint flavor and aroma without the sugar.
Philodendron Xanadu - grows to about 75-100cm high and keeps a neat form. Gorgeous lush foliage that would blend with the tropical feel of the frangipani. Would look nice in the front garden along the west boundary (under the neighbour's tree), mixed with Clivia.
Kentucky Colonel mint is great for Mint Juleps, Mojitos and more. Like all mints it should be confined to a pot. Mints grow better in pots that have a wide surface area rather than a lot of depth. A 14 inch Terra Cotta Bowl makes a perfect mint pot, at least for the first year. After that, it'll need to be divided and repotted using fresh soil each spring.
Scotch Spearmint - Also called "red mint", this is the spearmint variety used to flavor candies, gums, etc. by the commercial mint industry. This hard to find variety has a very strong and especially sweet spearmint aroma and flavor. Excellent culinary and tea variety.
