{"product_id":"mexicanna-water-lily-pond-plants","title":"Nymphaea 'Mexicanna'","description":"\u003cp\u003eThe name Nymphaea 'Mexicanna' is usually used in the trade for the yellow water lily species \u003ci\u003eNymphaea mexicana\u003c\/i\u003e, and the spelling varies a lot between sellers. This plant behaves differently from most hardy pond cultivars because it can spread by creeping runners as well as by rhizome growth. It makes floating pads and bright yellow flowers through the warmer months, and it is often grown for a more “wild” look rather than a neat, clumping patch.\u003c\/p\u003e\n\u003ch3\u003eAppearance\u003c\/h3\u003e\n\u003cp\u003e\u003ci\u003eNymphaea mexicana\u003c\/i\u003e has yellow flowers, typically smaller than the big hybrid cultivars, with blooms often described around 5–10 cm across. Flowers can be held higher than many hardy lilies when conditions suit it, which gives a lighter look above the pads. Leaves are smaller and can vary a lot in size depending on warmth and nutrition. Because it spreads by runners, it can create scattered pads across an area rather than a single tidy raft. In warm weather it can flower over a long season, opening through the day and often staying open later than many hardy hybrids.\u003c\/p\u003e\n\u003ch3\u003eCare Guide\u003c\/h3\u003e\n\u003cp\u003eTreat the plant with a bit of respect because of its spreading habit. If you want control, plant it in a solid container or a basket you can manage, and avoid letting runners escape into pond margins. Use a loam based aquatic compost and cap with gravel. Place it in full sun for the best flowering, though some sources say it will tolerate partial shade. Depth guidance varies, but many pond sellers place it quite shallow, often around 15–45 cm of water over the crown. Start on the shallow end so pads reach the surface quickly, then adjust if growth is weak. UK hardiness is reported differently by different suppliers, so for a typical UK garden it is safest to treat it as needing winter protection unless you have a deep pond that stays mild. Feeding in summer helps it flower and keeps leaf colour healthy.\u003c\/p\u003e\n\u003ch3\u003eSuitability for Garden Ponds\u003c\/h3\u003e\n\u003cp\u003eThis plant suits larger ponds or naturalistic wildlife ponds where you want a spreading yellow lily and you have room to manage it. The pads still provide shade and cover for fish and invertebrates, but the runnering habit means it can move beyond the original planting spot. In a small pond or a formal water feature, it is only a good idea if you keep it strictly contained. If you want a predictable clump and easy division, a named hardy yellow cultivar will usually fit better than \u003ci\u003eNymphaea mexicana\u003c\/i\u003e.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq\"\u003e\n\u003cp\u003e\u003cstrong\u003eIs Nymphaea 'Mexicanna' the same as Nymphaea mexicana?\u003c\/strong\u003e\u003cbr\u003eIn most pond plant listings, yes.
