Now that spring has sprung here it's fun to see what is growing in my DS's yard. Noticed this blooming the other day..reminds me of a magnolia,but the leaves don't look right to me. but then my thumbs still haven't turned green yet. LOL
A friend came over yesterday. From the pictures he suggested some sort of miniture magnolia. Sounds reasonable,I suppose,or some sort of wild native. The ladies who owned my place and DS's were great friends and did a lot of tromping around digging things up.
You have a young saucer magnolia tree (Magnolia soulangiana). I think maybe a "Pink Superba" variety. Although it could be "Liliputian", which have mainly light pink flowers. Saucer magnolias I've seen before are usually covered dense in flowers, more than leaves, in the early spring.
Your DS has a beautiful plant. You may want to consider improving the soil for more flowers next year. A number of state universities have great horticultural department web sites with information regarding ideal ph balances, insect suceptibility, and disease identification for a variety of tree specimens. Keep in mind that there is better information on specific plants growing in zones whose university is in the same zone. Such as the University of Hawaii has better information on palm trees than say the University of Maine. Being in zone 8, I suggest you check out California Polytechnic's site (http://selectree.calpoly.edu) for starters.
