"Velvet Love" Impatiens
Note that it's normal for Impatiens to drop a few leaves during shipping. It will quickly re-grow more once it is settled.
Pot size -- Transfer your plant to a pot approximately 1 quart to 1/2 gallon in size, with drainage holes. After a few months, it can go in a 1 gallon pot, which will hold it for at least a few months. Eventually it may need a 2-3 gallon container until you prune it shorter.
Soil -- Impatiens morsei likes fertile, well-draining soil. A typical mix is 2 parts potting soil to 1 part perlite or coarse horticultural sand (or pumice). If your tap water is "soft", meaning low in minerals, it is good to add a dash of agricultural lime (= dolomite lime.. not hydrated or quick lime). This is to simulate the limestone terrain that Impatiens morsei comes from. Only add approximately 1 teaspoon of lime per gallon of soil mix.
Watering -- Try to keep the soil evenly moist most of the time - but not soggy. Don't let the soil dry out completely.
Lighting -- Impatiens morsei prefers bright shade, or filtered sunlight. Avoid prolonged direct sun, unless it's early-morning sun.
Climate -- This Impatiens prefers mild temperatures. It should have a minimum of 50 degrees F (10° C) and at least about 45% humidity. I have no information on how much heat it can take, but it's possible that it may not thrive if temperatures are consistently above 85° F (30°C), particularly if nights are warm. Indoors, if your room humidity gets too low, consider using an ultrasonic room humidifier, which you can get at home improvement stores and thrift shops.
Fertilizing -- Your Impatiens likes average amounts of fertilizer. Use a general-purpose fertilizer, following the dosage and frequency on the package, or about every 2-3 months.
Pests to watch for -- aphids, spider mites (tiny "dots" and webbing under the leaves), whitefly, mealy bugs. Certain spider mites cannot be seen but cause deformities of the young leaves. Be careful when choosing chemical remedies, because some may harm the plant.
